Why Is My Air Conditioner Not Cooling?

Imagine that all of a sudden, during the peak of heat in Texas, your AC suddenly stops working. This is quite an unpleasant thought and experience to face. Stafford AC installation services in Bellaire, TX, are here to assist you with the knowledge that we’ve gathered during many HVAC repairs. 

What to do if the Air Conditioning System Starts Malfunctioning?

You need to calmly handle the problem and find out the reason that caused the sudden shutdown.

Malfunctioning can be indicated by loud noises, insufficient cooling, reduced airflow, and other issues. When your AC starts malfunctioning suddenly, you need to restart it. 

Follow the following steps to restart the air conditioning system:

  • Shut off the AC from the switch. Flip off the AC circuit breaker panel as well.
  • Find the red reset button somewhere in the outdoor unit. You can read the AC manual to find the button.
  • Press the reset button for around 2-3 minutes.
  • Flip on all the switches that you closed recently.
  • Wait for five minutes before turning on the AC from the thermostat. 

A word of caution – if the AC does not start after resetting, it is better to turn down the AC switches and call the air conditioning contractor in Bellaire, TX, immediately. 

Reasons Why my Air Conditioning System is not Cooling?

After restarting the air conditioning, the problem still prevails, so it is better to consult an expert technician. According to our expert professionals, the following explanations could be the reason behind inefficient cooling services: 

Air Filters

Air filters are always somewhere indulged in repair issues. All AC installation experts in Bellaire, TX, recommend the customers change the AC air filter once in two or three months. If you can not replace it, clean it accordingly once a week.

The air passes from the air filter, and all the dust, particulate matter, spores, pollens, and other invisible things get stuck in the air filter. As time goes by, these things get accumulated, and air cannot pass by because there are no holes for air to get through the filter. 

Thermostat Settings

Before panicking, it is always best to check the thermostat settings. Sometimes, unintentionally the settings get changed to off of fan mode. Even the temperature could be more than your preferred temperature, causing inefficiency.

If everything is alright and still does not work, you can check the circuit breaker switch near the indoor unit. Flip it up in case someone switched it down. 

Damaged Evaporator Coils

The evaporator coil is one of the essential components in the refrigeration cycle. An evaporator coil holds the refrigerant that adds the chilling element to the air, lowering the room temperature. If there is a leakage, the refrigerant dissipates, and the AC vents blow less cool air.

If you smell a chemical odor or sense a chillness around the outdoor unit, it is a sign of a refrigerant leak. Call the air conditioning contractor in Bellaire, TX, before the tank depletes the refrigerant.

Foliage and debris inside the outdoor unit can obstruct the cooling process. It is better to keep the surroundings around the outdoor unit clean and tidy.
